摘要
介绍了短程硝化反硝化的生物脱氮机理,综述了短程硝化反硝化过程中影响HNO2积累的主要因素游离性氨(FA)、pH、温度、溶解氧(DO)和污泥泥龄等,探讨了实现短程硝化反硝化的途径。
The principle of shortcut nitrification-denitrification was introduced. The results showed that the factors influencing the accumulation of HNO2 were free ammonia, pH,temperature, dissolved oxygen and sludge age. Then methods for achieving shortcut denitrifieation were put forward.
